UFS researcher publishes the highest-cited Maths paper in the world in 2017
An article by Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies received New Hot Paper status from Clarivate Analytics.
An article on Applied Mathematics, published by Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies in 2017, was recently named New Hot Paper by Clarivate Analytics.

Hot paper status
Essential Science Indicators (ESI) is a unique and comprehensive compilation of science performance statistics and science trends. Data is based on journal article publication counts and citation data from Clarivate Analytics that enables researchers to conduct ongoing, quantitative analyses of research performance and track trends in science. Covering a multidisciplinary selection of 1 2000+ journals from around the world, this in-depth analytical tool offers data for ranking papers, scientists, institutions, countries, and journals. 

ESI from Clarivate Analytics is updated every two months. The New Hot Papers, which are papers published in the past two years, are in the top one-tenth of one percent (0.1%) for their field and publication period. Prof Atangana’s paper had the highest cite count in the field of Mathematics. 

His article that received the New Hot Paper status is titled: “The new fractional derivative and application to nonlinear Fisher’s reaction-diffusion equation”.

The concept of fractional differential operators with non-singular kernel has captured the minds of several researchers in the past year due to their wider applicability in almost all fields of science, engineering and technology. The new fractional differential operators have opened new windows to model complex real-world problems that could not be modelled using the Newtonian and the well-known Riemann-Liouville fractional differential operators. 

“These operators are the way forward in modelling real-world problems in all disciplines, as they are able to include into mathematical formulation the effect of memory,” Prof Atangana said.

The Atangana-Baleanu fractional derivative
The professor developed a new fractional differential operator, called the Atangana-Baleanu fractional derivative. This derivative is able to describe real-world problems with different scales or problems that change their properties during time and space, for instance, the spread of cancer; the flow of water within heterogeneous aquifers, movement of pollution within fractured aquifers and many others.”

Luvo and Ryk inspire UFS student leaders

Dreams can come true and Luvo Manyonga’s story is the perfect example. It would make the ideal movie script. This is opinion of the businessman and former international swimmer Ryk Neethling.
 
The Olympic gold medallist and former World Champion and Manyonga shared their stories with new student leaders of the University of the Free State (UFS).

“I am so proud of this guy,” Neethling said. “And we are just half-way through this movie. The best is yet to come.” The 26-year-old Manyonga is the current Olympic silver medallist and World Champion in long jump. But he had to overcome huge obstacles as a former tik or crystal meth addict.

Not an easy road
The duo were guests for a session, Inspirational Stories of Lived Humanising Experiences, which was part of the university’s Student Leadership Training weekend for Student Representative Councils, Residence committees, Residence Assistants and Association Representatives in the Economic and Management Sciences Auditorium on the Bloemfontein Campus.

Manyonga, who is dating the Kovsie netball player Khomotso Mamburu, talked about growing up in Mbekweni township in Paarl, about his career and his setbacks.

After finishing fifth at the IAAF World Championships in Daegu, South Korea, in 2011 he started partying when he returned home. “I hooked up with the wrong friends and they introduced me to tik,” he said. “They told me: ‘Hey dude, you are drunk. Just take a hit and it will sober you up.’ I took it and it was nice, but that is where it started.”

Be surrounded by positive people  
Manyonga lost all his money and his sport was also suffering because of his addiction. “At the beginning of 2014 I started to realise that I was throwing my life away and I needed help. I went to reach out to people close to me and told them I had a problem.” He thanked Neethling, who helped him when he was at his lowest, his mother, the South African Sports Confederation and Olympic Committee, Tuks Sport and the High Performance Centre where he trains for the influence on his life.

Neethling’s advice to student leaders was to dream big, work hard, expand your network and find a mentor you can learn from.

“Always surround yourself with positive people,” he said. “You can succeed if you stay positive.”
